Abstract: A radio frequency identification communication method for collision reduction with low power consumption and radio frequency identification communication system using the same are provided in the present invention. The radio frequency identification communication method includes the steps of: setting different delay periods according to different RFID tags; in each preset time, enabling a RFID reader and detecting whether a RFID tag is on the RFID reader; detecting whether there is only one RFID tag on the RFID reader; when two or more RFID tags on the RFID reader are detected in a specific time slot, entering a suspend mode to stop providing RF power such that the RFID tags perform power on reset when the reader is enabled next time.

Abstract: A radio frequency identification integrated circuit for reducing pin counts and an RFID providing method thereof are provided in the present invention. The radio frequency identification integrated circuit includes a first IO pin, a second IO pin and a third IO pin. The method includes determining whether the coil is coupled to the first IO pin, the second IO pin and the third IO pin when the RFID IC is enabled; and determining the identification according to the voltage status of the non-coupled pin and the pins coupled to the coil.
